IIPE CONNECTION.

Specic'aton of Letters Patent. Application filed nly. 8, 1910. Serial No. 571,065.

Patented Jan. 3, 1911.

. Illinois, have invented new and useful Improvements in Pipe Connections, of which the following is a specification.

My invention relates to pipe connections for -use in connection with mains and fittings where the connection is made or has to be made through walls. While particularly designed for use in this connection, and `while especially adapted for this purpose, it will be evident upon a reading of the specification following that the joint ofiny invention may be used in many other situations.

At the present time in making connectidns from -basins and closets through walls to` mains, considerable4 diiiiculty is eigperienced in making a goed joint owing. tothela-ckf of free spacein 'the neighborhood of the basin or other fixture; Such fixtures'are usually placed quite close tothe' wal1,land many times in corners and outof the way places andl the space for making connections and for accommodating them after l theyare made is quite'limited. On this account,` as well as on accountof the particular kind of joints heretofore used, alinement and righting of the mains and fittings with respect to each otherhas heretofore in many caseb been extremely diiiicult. The pipes oi connections used in'connecting up'- baths and closets, are many times frail and: easily .bent or twisted, and' thisffurther increases the didicultyv of making. asatisfactoi'y joint.' @The result: of thi/s lis* often' afloose 'and unstable fitting or connectiomwhichfisfvery lliebte to lealr or tobreak'. and very'freqnentlyirattles too or vibra-tes in en annoying manner.- This latter trouble is found m factories and other buildings Where'fthe building' itself is in v.ease until it'bears'against joint whichmay be easily made and broken is of special value in making close connections, and in makingv connections with trapsl or other sucl'ifittings which have to be more or less frequently taken downand-1 cleaned out.

In the; accomplishmentof my invention I make useof the nipple of special form which I pass through the wall and screw thread into the main which is located adjacent to it. Adjustably mounted on. this nipple I'providea collar, equippedzwithl a countersunk set screw for clamping it in any desired position between the ends of the niple. I screwthread'on: the exterior surace of this collara. nut provided with a :footpiecewhich bears against the wall, and

with i an-.interiorly extending flange which its'f' close uponl the exterior-surface of the nipple. v.This flange- Ii'na -screw up` with g l the wall, and further-untilthe partstare' righted with respect .to each other and -viiith respect to the wall. Preferably I forni--tlie--footpieoe associated with the nutjin'theshapg'of an' integral out' Waifdly' extendingiiiage'- which fcovers the ,adjustablecollapfmnrasight and makes a close connection witliltlleA wall thus giving tothe fittings a neat'and attractive appearanceyas well as insuringacleanly joint conduciv--to-the best sanitatiom- The inne?.- end 4of the nipple I-fo'rm-'with an' enlarged intcriorly threaded portion provided4 with a packing recess, and attach the fitting, such ais' afaucet, to thsportion of' the nipple on the op osite side' of the-wall -from the main. Instea of the nipple I may thread the end of any si 4section 'to serve the same -purpose an equently this will be" done. M invention will be more fullfy underand ap reciated- 4from the ollowing description o the specific embodiment illustrated in the accompanying.A drawings, in whic'hlFigure 1 is a. sectional.- elevation of my 'invention, Fig. 2-isia 4artial sectional elevation of a modified oim, and Fig. 3 is a section takenv onf line 3--3- of .F ig. 2, the footpiece or clamping` flange being omitted for the sake`of clea-iness.

10 is the wall, adjacent to which on one sidex is the main 11, and on thefother'sideo which is the fitting .12, shown in this instance as a faucet. This fitting is connected tothe main 11 by a ,nipple 13 which is screx'v threaded into the tee 14: of the maiii and provided on the end to which thev faucet is adjusted position on the nipp e.

f thus hidin attached with an enlarged interiorly screw threaded portion 15. This portion is provided with a packing recess 16 in which is confined a 'packing 17 by the flange 18 of the attached faucet'12. Mounted on the body of this nipplebetween its ends, is an adjustable collar19 equip ed with a 'counter-sunk set screw 2O for c ampino it inany Screw threaded to the exterior surface of Athis collar is a nut 21 provided with a foot-piece 22 in the ormof an `integral flange, which extends outwardly and bears upon the wall 10. An inwardly extending flange 23 projects from the body of the nut into close contact with the outer surface of the nipple, the colla and the aperture 24 through w ich the nipple passes from sight.

spect to each other and the wall.

The joint of my invention is assembled f, with facility and ease in the following manner. The nut 21 and its attached parts and the adjustable collar 19 are placed on the nipple inthe' order shown in Fig. l, and the nipple is then passed through theopening 24 in the wall and screw threaded into the tee 14 by means of a. wrenchapplied on the nut 25 on the enlarged portion 15. Thereafter the collar 19 is moved tothe proper position for the nut 21 yto be vbest mani ulated and clamped in position by driving home set screw 20. Nut 21 is then run up on the collar 19 until it bears against 'the wall 10, and further until it rights the main 11 andthe fitting 12 with respect to each other and with respect to the wall, and stays them in sturdy and rigid relation with .re-

A nice close contact is made by the foot-piece or flange 22 with the wall, and in this form it covers the aperture 24 and the collar 19 and gives the fittings a very neat and attractive appearance.- The connection made to the main in this manner, the fitting or the faucet 12 is inserted into the end of the nipple and screwed home and to an upright position. If desired this faucet or othervftting may be placed in the nipple, before the collar 19 land the nut 21 have been manipulated to right the nip le and the main.

Figs. 2 an 3 show a modification of my invention. This modification consists primarily in providing the collar 19 with -lateral extensions 26 which projectbeyond the borders of the opening 24 in the wall 10, and

bear against the inner Surface of wall 10 in' the same manner as does the foot-piece 22.-

By this provision a certain amount. of thc strainincident to righting the parts and ,staying them in position, lis taken. by the collar 19, the parts being righted by pulling upon the nipple 13 from the inner end and -then shoving: the collar up until the feet' come into contact with the waltlO. and

.piece or flange 22 may be made of sheet metal as is very common in pipe connections now in use. This-form of my invention is especially7 adapted for use ui connection with any form of pipe section. It is ot'.

course now evident that both forms of my invention may be so used.

I desire to have it understood that the specific embodiment illustrated by `me in the drawings,'and described by me in the specification is illustrative only, my inyention being capable of many modifications, and of use in many situations other than that mentioned without in any wise departing from its-generic spirit. I desire to cover all such modifications in the annexed claims.

What I claim is 1.1The combination for connecting a fit- 4ting on one side of a wall to a main on the other, of a pipe section adapted to be di.`

rectly connected with the main provided with an adjustable collar, a nut screw threaded to said collaig'anda foot-piece associated with said nut.

' 2. In combination a main onone side of a wall, a fitting on the opposite side of said wall,'. a pipe .section directly connecting said fttin tosai'd-main, an adjustable collaron sai ypipe section independent of said main vand fitting, a nut screw threaded on said collar, and afoot-piece associated with Vsaid nut .and bearing on said wall whereby said main and fitting are righted with respect to eachother and stayed to said wall.

3. In combination a main on one side of a wall, a fitting on the opposite side of said wall, a pipe section directly connecting said lOl fitting to said main, an adjustable collar l separate from said main and fitting on said pipe section, a countersunk 4set screw associated with said collar for clamping the same iii position, a nut screw threaded on said collar, a' foot-piece associated with said nut and bearing on said wall whereby said main and fitting 'are righted with respect to each other and-stayed tosaid wall.

4. .In combination a main on one side of a wall, a fitting on the opposite side of said wall, a pipesection -connecting said fitting to said main, an adjustable collar on said.

pipe section, lateral extensions projecting directly from said collar into engagement with said wall, a. nut screw threaded on said collar, and 'a foot piece associated with said 'nut and,bearing on said wall whereby said j main and fitting may be righted with respect to eachother and stayed to said wall.

5. In combination a main on one side of a wall, a lpipe section proj eating through said wall, and screw threaded into said inain atf f itsfone cnd,said pipe sectioii'having an enlarged interiorly scrcwthreaded portion at the other end, a packing recess in said end,

.a fitting screw threaded into said end, a

packing in said recess between the end of said pipe section and the fitting, an adjustable collar mounted on said pipe section hetween its ends, means for clamping said co1- lar in adjusted position, and a ange adapted to bear against the wall screw threaded to said collar and completely hiding the same when in position.

6. In combination a mainadjacent to a Wall, a pipe section screw threaded into said main and passing through said wall, said pipe section having an enlarged portion on" the end away from said main, an adjustable-'f collar mounted on said pipe section between its ends, means for clamping said collar in position, and a ange screw thizeaded to said collar and bearing on said wa11.'
